APPARATUS FOR CEMENTING SOLES TO SHOES.

` Application mea september s, .192'.5. serial No. 54,986.

This invention relates to` a novel method of cementing soles to shoes and also to a device for conducting this method.

When shoes are worn, it is common to have them resoled. It is general practice to attach the new Soles to shoes either by' nail- When a' new sole is nailed'to the shoe the inner Sole thereof is damaged, and when a new sole is sewed to the Shoe the welt thereof is damaged.

It is an 'object of this invention to provide a method of soling shoes which does not damage the welts of inner soles of the shoes but lwhich 'involves cementing the soles in place. e lt is another object of this invention to provide a method of the character mentioned in which the new sole is held pressurably in engagement withthe shoe while the cement employed for the attachment of the sole is setting.

lt is another object of 'this invention to provide a device for conducting this method.

It is also an object of this invention to provide a shoe solingdevice having a pliable bag lilled with a mobile substance2 this preferably being a liquid against which a shoe is forced after it has had a sole properly placed against the inner sole thereof, while the cement used is setting.

It is a further object of this invention to provide a shoe soling device having a ibiovel form of box for holding the pliable It'is a further object of this invention to provide a pliable bag having relling means.

It is another object ofvthis invention to provide a shoe soling device havin an insert form which is placed inthe soe, this' insert` form being designed so that the pressure may be ei'ectively applied to the bottom of the shoe and the sole.

lt is another object of this invention to provide a shoe soling device having an insert form which is expansib'le and has anextending rim so that pressure may be applied to the extremities of the bottom .of the shoe and the sole.

4Other objects and the advantages of the invention will appear in the following de,- scription.

Referring to the drawing in which I illustrate my invention,

Fig. 1 is a plan view of the shoe soling i device o f my invention.

Fig. 2 is an elevational view partially sectioned showing the shoe soling device of Fig. 1. y

y ig. 3 is a section taken on the line 3-3 of Fig. 2.

Fig. 4 is a section taken on the line 4 4 of Fig. 2.

The form of my invention shown in the drawing comprises a table or base plate 11 having an upper face 12 from which there extend posts 13, these posts 13 being rigidly secured to the table 1l as by threaded prjections 14 extending into cavities of the table 11, as shown-:in Fig. 2. Upper reducedends 16 ofthe vertical post 13 extend through openings 17 formed at the opposite ends of a head 18. Nuts 19 are threaded onto the projecting ends of the reduced ends 16 for clamping the lower face of the head 18 against annular shoulders 21 of the post 13. The head 18 has a threaded passage 22 through which a screw 23 extends, this screw 23 having a hand wheel 25 by which it may be rotated and advanced in either direction andv having a shoe f 27 attached at the lower end thereof.

A bag retaining box 29 is supported on the upperface 12 of the table 11. This box 29 has a bottom wall 30 from which there extend in an upward 'direction end walls 31 and side walls 32. The side walls 32 are declined at the left end thereof, as indicated at 33 in Fig. 2, so that the left end wall 31` is somewhat shorter than the right vend wall 31. A continuous retaining lip 36 extends ibli liquid 39 by means of a valve 43 which 38 is placed in the i extends therefrom through an opening 44 in a side wall 32 of the box-29. When the bag is filled with liquid, as shown in the drawsociated with a common type of spreading' arrangement and it is not necessary to show the details thereof. The insert form 46 comprised of the `halves 47 has a foot portion 49 from which there extends a rim 50 as shown in `Figs.l 3 and 4. Extending forwardly from the upper parts of the halves 47 are, arms 52 The insert 'form 46 is placed in a shoe 54, as shown in Figs. 2 and 3. The shoe 54 has been previously worked upon and has a new sole 55 temporarily held in engagement with the lower face of a bottom or inner sole 56 of the shoe 54 as by a single nail. Illhe lower face of the inner sole 56 is coated with a suitable cement and the upper face of the sole 55 is likewise coated with a suitable cement before these faces are brought into engagement. 'llhe insert form 46 is extended into the forward part of the shoe 54 and the halves 47 are expanded' sidewise, as

shown in Fig. 3, so that the rim 50 will extend to the extremities of the inner sole 56. The insert form 46 may be held in the forward part of the shoe by means of an adjustable arm r58 which extends rearwardly from the inset form 46 and has an engager 59 secured at the end thereof, which engager 59 is adapted to contact a rear part of the shoe 54.

After the form has been thus installed in the shoe 54, this shoe and form are placed as shown in Figs. 2 and 3 of the drawing. The lower face of the sole is placed on the upper part of the pliable bag 38 and the arms 52 are positioned below the threaded shoe 27 of the screw 23. rll"he screw 23 is then advanced downwardly by operating the handvwheel 25 so that the threaded shoe 27 will engage the arms 52 and force the form in a downward direction. This forces the form against the inner sole 56 of the shoe 54 and forces the sole 55 firmly against the pliable bag 38. As shown clearly in Fig. 3 the bag 38 readily conforms to the contour of the inner sole and the bottom of the form 46, and the sole 55 is forced into conformity with this shape. rlhe liquid 39 in the bag 3 8 exerts a force upwardly against the sole of the shoe 55, which force is distributed equallyover the area of the sole.

As shown inllig. 2 the side walls 32 of the box 29 are declined so as to make room for the heel of a shoe. lin cementing soles to ladies shoes it is necessary for the bag to my neaaeei follow the contour of 'the bottomof the shoe up into the space adjacent to the heel. By declining the side walls 32 it is possible to allow the heel to rest over the bag and for the bag to readily follow the contour of the bottom of the shoe.b rllhe cement is allowed to set while the sole 55 and the inner sole 56 are held pressurably in engagement with device shown in the drawings. My invention p f does not damage the shoe. in any way and consequently the shoe maybe resoled a great number of times. When soles are nailed to the shoe and when sewed to the shoe, the inner sole or the welts are vdamaged each time and consequently the life of the shoe is considerably shortened. rllhe shoe soled in the fashion of my invention is vfound to be very flexible and will retain its shape. en

sewing and nailing soles to shoes, the shape' of the shoe is often distorted.`
